    摘要:
    我们开发了一种直接有效的合成环霉素 0 的途径,使用亚砜糖基化反应形成糖苷键。在完成环霉素 0 的合成过程中,我们开发了新的糖基化条件,以改善亚砜反应的结果。这些条件包括添加清除苯亚磺酰三氟甲磺酸酯的试剂,三氟甲磺酸苯硫酯是在异头亚砜与三氟甲磺酸酐活化后形成的高反应性副产物。

  • Method of forming multiple glycosidic linkages in a single step
    申请人:The Trustees of Princeton University
    公开号:US05635612A1
    公开(公告)日:1997-06-03
    The invention relates to methods that permit the rapid construction of oligosaccharides and other glycoconjugates. Methods for forming multiple glycosidic linkages in solution in a single step are disclosed. The invention takes advantage of the discovery that the relative reactivity of glycoside residues containing anomeric sulfoxides and nucleophilic functional groups can be controlled. In another aspect of the invention, the reactivity of activated anomeric sugar sulfoxides is utilized in a solid phase method for the formation of glycosidic linkages. The methods disclosed may be applied to the preparation of specific oligosaccharides and other glycoconjugates, as well as to the preparation of glycosidic libraries comprising mixtures of various oligosaccharides, including glycoconjugates, which can be screened for biological activity.

  • The synthesis of daunosaminyl ε-rhodomycinone, daunosaminyl 10-epi-ε-rhodomycinone, daunosaminyl ε-pyrromycinone, and 10-descarbomethoxy-ε-pyrromycin
    作者:John M. Essery、Terrence W. Doyle

    日期:1980.9.1

    The epimerisation at C10 of ε-rhodomycinone by aqueous alkali treatment of its 6,7-acetonide is described. Daunosaminyl ε-rhodomycinone and daunosaminyl 10-epi-ε-rhodomycinone were prepared and compared with regard to their antibacterial properties. Daunosaminyl ε-pyrromycinone and 10-descarbomethoxy-ε-pyrromycin were synthesized and their antitumor properties were compared with some naturally occurring glycosides of ε-pyrromycinone.
